Abstract (en)
Embodiments provide a method for processing a disparity value for an image element in a first image with respect to a second image. The method may include determining an intensity disparity histogram, which includes, for each intensity value of a plurality of intensity values and each disparity value of a plurality of disparity values, a frequency value indicating the number of image elements having the respective intensity value and the same disparity value; selecting a tuple of a frequency value and an associated disparity value, for which the frequency value fulfils a predefined criterion; determining a first weighting factor dependent on the frequency value of the selected tuple; determining a texture value for the image element, the texture value representing an intensity value variation over a neighboring region of the image element in the first image; determining a second weighting factor dependent on the texture value of the image element; and determining an amended disparity value for the image element dependent on the disparity value for the image element and the first weighting factor, the second weighting factor, and the disparity value of the selected tuple.
